Yaki Onigiri Ingredients

• Get ready to whip up these delightful rice balls with just a few simple ingredients!

For the Filling

Canned Tuna – Provides the primary protein source; be sure it’s well-drained for the best texture.
Kewpie Mayo – Offers creaminess; you can swap this for regular mayo if desired.
Sriracha – Adds heat and flavor; adjust to your taste or substitute with another hot sauce.

For the Rice

Cooked Sushi Rice or Japanese Short-Grain Rice – Forms the base of your Yaki Onigiri; its sticky nature is essential for shaping.
Rice Vinegar (1 tbsp, optional) – Enhances flavor and helps the rice hold together; it’s optional but recommended for that authentic touch.
Furikake (2 tbsp) – Adds umami flavor; if unavailable, sesame seeds make a great substitute.

For Grilling

Cooking Oil – Used for frying; a neutral oil like canola works best to achieve that crispy exterior.
Light Soy Sauce (2 tbsp) – Provides a delicious savory element; for gluten-free options, tamari can be used.

For Wrapping

Nori Seaweed Strips (6) – Adds a delightful sea flavor and helps to hold your onigiri together; feel free to omit if you prefer.

Step‑by‑Step Instructions for Spicy Tuna Yaki Onigiri

Step 1: Prepare the Tuna Filling
In a medium bowl, drain the canned tuna thoroughly and then add the Kewpie mayo and Sriracha. Mix the ingredients together until well combined, ensuring the tuna is coated with the creamy mixture. The filling should be smooth and slightly spicy, ready to surprise your taste buds when stuffed inside the onigiri.

Step 2: Mix the Sushi Rice
In another bowl, combine the cooked sushi rice with rice vinegar and furikake (if using) until the rice is evenly seasoned. This step should take about 1-2 minutes, and the rice should be slightly sticky, making it easier to mold later. If your rice is cold, consider briefly microwave it to warm it up for better handling.

Step 3: Shape the Onigiri
Utilizing an onigiri mold, fill it halfway with the seasoned rice, then create a small indentation in the center for the tuna filling. Spoon in a generous amount of the spicy tuna mixture before covering it with more rice. Press the mold firmly to shape the rice ball into a compact form. If you don’t have a mold, you can shape the onigiri by hand, forming a triangle with wet hands to prevent sticking.

Step 4: Grill the Onigiri
Heat a nonstick skillet over medium heat and add a suitable amount of cooking oil to prevent sticking. Once the oil is shimmering, carefully place the shaped onigiri in the skillet, allowing them to grill for about 3-5 minutes per side. Keep an eye on them, ensuring they develop a lovely golden-brown crust that adds both texture and flavor to your Spicy Tuna Yaki Onigiri.

Step 5: Brush with Soy Sauce
After achieving a crispy exterior, brush the grilled onigiri with light soy sauce while still in the skillet. This will enhance their savory flavor and give them an additional few minutes on the heat to soak in the soy sauce goodness. Flip the onigiri again and grill for another 1-2 minutes until beautifully caramelized.

Step 6: Serve the Yaki Onigiri
Once grilled to perfection, remove the onigiri from the skillet and wrap each piece with a strip of nori, if desired. This adds a delightful contrast in flavor. Serve your delicious Spicy Tuna Yaki Onigiri warm, and consider pairing them with a light salad or a warm bowl of miso soup for a satisfying meal.

Expert Tips for Yaki Onigiri

Sticky Rice Rule: Ensure your sushi rice is sticky enough; too dry, and it won’t hold its shape. A quick warm-up helps if using leftovers.
Grilling Space: Don’t overcrowd the skillet while grilling the onigiri. Allowing space ensures even cooking and achieves that perfect crispy texture.
Perfect Fillings: Feel free to experiment with fillings! If you don’t have canned tuna, consider using shredded chicken or even mashed avocado for a vegetarian version.
Watch the Heat: Cooking on medium heat is key. Too high, and the outside burns before the inside is warm; too low, and it won’t crisp up properly.
Soy Sauce Glaze: Brush the soy sauce on during the last few minutes of grilling for an added layer of flavor that brings out the savoriness of the Yaki Onigiri.

What to Serve with Spicy Tuna Yaki Onigiri?

Indulging in these crispy rice balls opens the door to a world of delicious pairings that elevate your meal experience.

Warm Miso Soup: A comforting bowl of miso soup brings warmth and a savory depth that complements the flavors of the onigiri beautifully.
Light Sesame Salad: Fresh greens tossed with a sesame dressing add a crunchy texture and brightness, balancing the savory richness of the rice balls.
Pickled Vegetables: Garnish your plate with vibrant pickled vegetables for a tangy contrast that enhances each bite of the spicy tuna filling.
Crispy Edamame: These nutritious beans, lightly salted and grilled, provide a satisfying crunch and fresh flavor that pairs wonderfully with onigiri.
Cucumber Salad: A refreshing cucumber salad with a dash of rice vinegar offers a cooling effect against the spicy tuna, creating a delightful balance.
Sake or Green Tea: Sip on a chilled sake or a warm cup of green tea while enjoying your onigiri for a true taste of Japanese dining tradition.
Fruit Desserts: Finish on a sweet note with seasonal fruit, like mango or strawberries, which add a natural sweetness and lightness to round out your meal.

Make Ahead Options

These Spicy Tuna Yaki Onigiri are fantastic for meal prep, allowing you to save time on busy days! You can prepare the filling (tuna mixture) and seasoned rice up to 24 hours in advance; just store them in separate airtight containers in the refrigerator. To maintain quality, ensure the rice keeps its stickiness by sealing it tightly to prevent drying out. When you’re ready to enjoy, simply shape the onigiri and grill them as instructed. This not only saves time but also results in delicious, crispy rice balls that are just as tasty as if made fresh!

How to Store and Freeze Yaki Onigiri

Fridge: Keep leftover Yaki Onigiri in an airtight container for up to 3 days. This will help maintain freshness and flavor, making them great for quick snacks or lunches.
Freezer: For longer storage, freeze the onigiri in a single layer on a baking sheet until firm, then transfer to a freezer bag for up to 2 months—perfect for meal prep!
Reheating: To reheat, place the onigiri in a nonstick skillet over medium heat with a splash of oil. Cook for about 3-5 minutes per side until crispy again, or use an air fryer for convenience.
Wrapping: If using nori, it’s best to wrap and enjoy the Yaki Onigiri fresh. If stored, keep nori separate and add just before serving to maintain its crunch.
